The Nintendo Entertainment System (ファミコン, Famikon, Famicom), commonly abbreviated as NES or Nintendo, was the first home gaming console manufactured by Nintendo. It was the system that saved the industry after the Great fall of video games of 1983. It was the first home console that Nintendo sold worldwide. In South Korea the console was known as the Comboy, and was distributed by Hyundai Electronics.

The NES debuted in Japan as the Famicom (Family Computer) in 1983. After selling over 2.5 million units by the end of 1984, Nintendo decided it would bring its console to North America. They first tried negotiating with Atari to have them release it, but the deal fell through, so Nintendo decided that they would release the console themselves.

The Famicom was difficult to pitch to retailers due to the current video game market being oversaturated with poor titles and low consumer interest. After tweaking the system a few times, Nintendo finally pitched the console as the Nintendo Entertainment System and emphasized its toy-like features such as the Robot Operating Buddy (R.O.B.) and the Zapper light gun. Retailers finally began to take interest and the system debuted in test markets in New York City and Los Angeles before eventually being released all across the United States.

Gradually, the competition began to catch up and the next generation of home consoles, such as the SEGA Genesis and Nintendo's own Super Nintendo Entertainment System, began to overtake the NES's market share. Finally, after a full decade of production, the NES was formally discontinued in the U.S. in 1995. By this time, over 60 million units and over 500 million games had been sold throughout the world.

In Japan, the Famicom recieved a disk drive add-on called the Famicom Disk System. The Disk System connected to the Famicom via an expansion slot on the bottom of the console, and used rewritable double-sided floppy disks ("Disk Cards") to store game data. A RAM cartridge, which served as the Disk System's disk buffer, was plugged into the cartridge slot. The FDS also added an FM synthesis channel to the Famicom, allowing for enhanced sound.

The Disk Cards were the first Famicom games to allow players to save their game progress. Also, the disks could store more data than the cartridges of the time. This allowed for sales of cheaper and larger games as manufacturing a disk was much less expensive than manufacturing a cartridge. Also, games could be purchased and written to blank disks at kiosks found at many locations.

Many FDS games were later re-released as regular Famicom cartridges, using password saving or battery-backed memory in lieu of the disks' rewritable memory. However, the enhanced FM synth sound was not carried over to cartridge games. While there were plans to release the Disk System in North America, this never happened and all Disk System games released in North America were released as regular cartridges. The bottom expansion slot still remained, however.
